Abstract

The utility model relates to a cotton picking expansion roller relating to the technical field of agricultural machinery and comprising a tubular shaft and a bow tooth, wherein the bow tooth is in a shape formed by bending one end of a cross rod downward by 90 degrees, and the bent end is fixedly arranged on the side wall of the tubular shaft; the bow tooth consists of a main bow tooth and an auxiliary bow tooth; and the end parts of the other ends of the main bow tooth and the auxiliary bow tooth are oppositely arranged. The cotton picking expansion roller has reasonable and compact structure and high clean picking rate, no existence of broken branches situation, is very convenient in use, and low in manufacturing cost of the equipment; and when the cotton picking expansion roller rotates, the bow-shaped bow tooth extends into a cotton plant for picking and has a conveying action opposite to the advancing direction of a cotton picking machine to the cotton plant so as to avoid blockage, thus greatly improving the working efficiency of picking cotton.

Description

A kind of cotton picking roller

Technical field

The utility model relates to the farm machinery technical field, refers in particular to a kind of cotton picking roller.

Background technology

At present, results cotton both domestic and external does not have in harvest operation selectively with cotton picker gathers cotton and bell shell together, and this kind cotton picker has comb-tooth-type, brush board formula and rubber to dial types such as formula.The comb-tooth-type cotton picker is upwards to curry from the cotton plant root by broach cotton and bell shell are combed together, and its shortcoming is that disconnected branch bar is more, is not suitable for the harvest operation of Cotton in China cropping pattern.It is to dial cotton plant by roller from the cotton plant both sides to carry out cotton picking that brush board formula and rubber are dialed the formula cotton picker, it all is flexible being characterized in dialing device, elasticity is dialed device and is difficult to enter cotton plant inside and dials, make the cotton picking of cotton plant inside not go up, cause the cotton pick up rate low, and dial device and rupture easily.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of cotton picking roller, can effectively solve the problem that above-mentioned prior art exists.

To achieve these goals, the technical solution adopted in the utility model is: the utility model discloses a kind of cotton picking roller, it comprises tubular axis and bow tooth, described bow tooth be cross bar a wherein end down the shape and its bending end that form of 90 degree bendings be fixedly installed on the sidewall of tubular axis, the bow tooth is divided into main bow tooth and auxilliary bow tooth, and main bow tooth is oppositely arranged with the end of the auxilliary bow tooth other end.

As preferably, main bow tooth all tilts with tubular axis with auxilliary bow tooth.

The beneficial effect that this utility model is brought is: the utility model provides a kind of cotton picking roller, its reasonable and compact in structure, the pick up rate height can not exist the more situation of disconnected branch bar to take place, and uses very convenient, the low cost of manufacture of equipment, when cotton picking roller rotates, when arch-shaped teeth stretches into the cotton plant harvesting, cotton plant had the conveying effect opposite with the cotton picker direction of advance, avoid stopping up, thereby greatly improved just cotton operating efficiency.

Fig. 2 is the side structure schematic diagram of the utility model embodiment.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Shown in Fig. 1-2, as a kind of embodiment of the present utility model, this cotton picking roller comprises tubular axis 1 and bow tooth, described bow tooth be cross bar a wherein end down the shape and its bending end that form of 90 degree bendings be fixedly installed on the sidewall of tubular axis 1, in the present embodiment, described bow tooth is the knee shape that a cross bar down is bent into 90 degree.Main bow tooth 3 all tilts with tubular axis 1 with auxilliary bow tooth 2, can improve the guiding effect of cotton branch bar, reduces disconnected branch bar, improves operating efficiency.The bow tooth is divided into main bow tooth 3 and auxilliary bow tooth 2, and main bow tooth 3 is oppositely arranged with the end of auxilliary bow tooth 2 other ends, and both paired spirality distribution of shapes are on tubular axis 1.Stretch into cotton plant inside for the ease of the bow tooth and pluck harvest operation, described main bow tooth 3 all can adopt rigidity or elastomeric material to make with auxilliary bow tooth 2.

Claims

1. cotton picking roller, it is characterized in that: comprise tubular axis and bow tooth, described bow tooth be cross bar a wherein end down the shape and its bending end that form of 90 degree bendings be fixedly installed on the sidewall of tubular axis, the bow tooth is divided into main bow tooth and auxilliary bow tooth, and main bow tooth is oppositely arranged with the end of the auxilliary bow tooth other end.

2. a kind of cotton picking roller according to claim 1 is characterized in that: main bow tooth all tilts with tubular axis with auxilliary bow tooth.
